Abstract

Behavioral conditioning in Lymnaea increased the amount of immunolabeling in the central nervous system for the memory-associated protein calexcitin. The staining level of anti-calexcitin positive neurons was always stronger in conditioned animals than in naive animals. In the visuo-vestibular conditioned animals, right-parietal and visceral group neurons as well as withdrawal-related neurons were positively stained with anti-calexcitin antibody. In taste-aversion conditioned animals, right-parietal visceral G-group neurons and withdrawal-related neurons were selectively stained. These neurons are candidate neurons for modulation by these conditioning paradigms.
